The deceased former CEO of embattled Bosasa/African Global Operations, Gavin Watson, was due to testify at an inquiry into his tax affairs on Tuesday.

News24 understands that the inquiry, led by advocate Piet Marais SC, was supposed to hear from Watson as part of an investigation by the South African Revenue Services (SARS) into his tax compliance. The inquiry flowed from testimony at the commission of inquiry into allegations of state capture.

More than 20 witnesses are expected to appear before the inquiry, which is a process closed to the public as it relates to tax matters, which SARS is under legislative obligation to keep confidential, News24 earlier reported.

These payments were described by former Bosasa chief operations officer Angelo Agrizzi during testimony before the commission as being an incentive for staff members to keep quiet about alleged bribery practices that continued for years.

Govt contracts worth R12bn

Agrizzi estimated that tens of millions of rand were paid in bribes to, mainly, Department of Correctional Services and Department of Social Development officials in exchange for lucrative multibillion-rand tenders.

He spent more than 10 days on the witness stand, delivering bombshell testimony of alleged illegality involving corrupt tenders, bribes and how the company had allegedly bribed its way out of trouble after being in hot water with the National Prosecuting Authority.

From 2006 to date, Bosasa won government contracts worth an estimated R12bn, National Treasury data shows.

In 2007, the Special Investigating Unit (SIU) finalised a report that found bribes were paid to former correctional services commissioner Linda Mti and former correctional services chief financial officer Patrick Gillingham in exchange for fencing tenders worth hundreds of millions of rand.

Gillingham and Mti, together with Agrizzi and other Bosasa staff, were charged in February this year with several counts of money laundering and violations of the Public Finance Management Act, as well as the Prevention and Combating of Corrupt Activities Act.

Agrizzi, former Bosasa chief financial officer Andries van Tonder and senior Bosasa manager Frans Vorster, who were also charged, all appeared before the Zondo commission to give evidence against Bosasa.

Tenders worth R2bn

The five men face charges relating to four tenders, worth roughly R2bn, which correctional services awarded to Bosasa between May 2004 and December 2005 and alleged bribes paid to Mti and Gillingham. The transactions described in testimony before the Zondo commission all carry tax implications.

Bosasa changed its name to African Global Operations in 2017, in an attempt to avoid the public scrutiny that the Bosasa name carried.

The name change also coincided with a renewed vision inside the company to expand its business into Africa with President Cyril Ramaphosa's son, Andile, and Chinese surveillance technology giant Dahua Technology.

But the implications may run far wider than just Watson's personal tax affairs.

Despite allegations of corruption surrounding Bosasa being in the public domain since 2007, former ANC treasurer general Zweli Mkhize admitted that the party continued to accept donations from the company.

Donations carry tax implications for both parties involved and could spell trouble for the ANC if tax donations were not properly managed.

A controversial donation of R500 000 was also made to Ramaphosa's presidential campaign by Watson in the run-up to the ANC's national elective conference.
